We have given the clock our son to school starting. He finds great, especially the 'second hand' of a small plane that always flies in a circle. I think the black hour numerals on a dark blue background a little difficult to read; if I had seen the clock in Natura, I would possibly me. for a different color chosen (although I really find very beautiful blue). We are very satisfied; in daily use, the clock must be to prove themselves, but I am optimistic :)
